Cell phone becomes especially helpful when people get into critical situations&period; In case of emergency a timely call can save somebody's life&period; Unfortunately&comma; there are still some places where one can find themselves "out of coverage"&period; Usually those places are either too far from the cell phone base station or located inside underground constructions&comma; for example&colon; · Parking lots&comma; tunnels· Big stores&comma; office buildings· Cars&comma; boats etc&period; · House in remote areas etc

The outside antenna catches the low signal from the mobile base station and delivers it to the cell phoneAmplifier through the connection cable &lpar;coax&rpar;&period; After the signal is accepted by the phone amplifier&comma; the device amplifies it&period; Then this amplified signal goes through the connection cable &lpar;coax&rpar; to the inside antenna&period; And after that&comma; the amplified signal transmits to the cell phone&period;

How should you install repeater &lpar;very easy and simple&rpar;&colon; Step 1&colon; Use your mobile phone to test signal strength outside house or on roof&comma; -70dbm is the basic requirement &lpar;full bar&rpar;&period;

Step 2 Install outdoor antenna in that location and keep adjusting&comma; point it to signal tower station&comma; try to get best signal&period;

Step3&colon; Run outdoor coaxial cable into building in a convenient location to connect with signal repeater&period;

Note&colon; Connect outdoor &lpar;BTS&rpar; port with outdoor antenna&comma; connect indoor ANT&lpar;MS&rpar; port with indoor antenna&comma; outdoor antenna is mounted at a higher position&period; Both antennas should be 10 meters far away from each other at least&period; Indoor and outdoor antenna must be separated by wall&period;
